Patented Feb. 23, 1932 UNITED STATES PATENT OFFICE CALVIN CAMPBELL, 01DENVER, COLORADO, ASSIGNOR TO THE COLORADO FUEL AND IRON COMPANY, OFDENVER, COLORADO, A CORPORATION OF COLORADO WALL AND CEILING BOARD CLIPApplication filed February 7, 1928.

This invention relates to fastenings for composition boards of the kindused in the construction of walls and ceilings of buildings and otherstructures and its primary object is to provide a clip of simpleconstruction which is readily applied and which provides a safe,reliable and rigid means for fastening wall or ceiling board to metalstuds, joists and other flanged structural supports.

A further object is to provide a clip of the above described characterwhich is made of a single piece of bendable metal with or without a rustproof coating.

Another object resides in providing a clip for fastening wall or ceilingboards that can be applied to one or both sides of a flanged structuralsupport.

A further object is to provide a clip adapted for fastening wall orceiling boards at a definite distance from an edge of the structuralsupport or flush with said edge in accordance with different positionsof the boards with relation to the supports.

Another object is to provide a clip applicable to flanged supports ofdifferent widths; and still further objects reside in details ofconstruction as will be fully described in the course of the followingdescription.

An embodiment of the invention has been illustrated in the accompanyingdrawings in which like characters of reference designate correspondingparts throughout the views, and in which,

Figure 1, represents a perspective view of the clip;

Figure 2, a face view of ceiling-boards adjoining one another at adistance from an edge of a flanged support and fastened together and tothe support, by means of the clip;

Figure 3, a section taken on the line 33, Figure 2;

Figure 4, a section similar to Figure 3, showing the method of applyingthe clip to a board flush with a face of the flanged support; and

Figure 5, a section on the line 55, Figure 4.

Referring further to the drawings, the clip as illustrated in Figure 1,comprises a single Serial No. 252,532.

length of sheet metal bent to provide abodymember 5 and endanembers 6 atright angles thereto. The three members are cut and portions thereofbent at right angles to provide two pairs of arms 7 at opposite ends ofthe body-member, flanges 8 projecting outwardly from the end-members andflanges 9 extending inthe planes of the end-members.

The arms 7 and the flanges 8 are formed by two parallel slits in the endmembers, and the flanges 9 are formed by U-shaped cuts in theend-portions of the body-member. The flanges 8 are partially split as at10, to provide tongues 12 which in practice are bent along lines 13 thatmay be defined by perforations or other weakening means; and the flanges9 have similar rows of perforations 14 defining tongues 15.

Now referring to Figures 2 and 3 of the drawings, the referencecharacter 16 designates a joist, stud or other structural support madeof flanged metal. The support as shown, is of channel section, and hastwo flanges 17 at the ends of a body-plate, but it is to be understoodthat the clips may be applied as well to supports of different forms.

Wall or ceiling boards 18 resting against the flanges of the supportmeet at a distance from the edges of the same and they are secured attheir abutting ends to each other and to the flanges of the support bymeans of the hereinbefore described clips in the following manner:

The body-member of the clip is placed flat against the body-plate of thesupport and the arms at opposite ends thereof are bent around the outeredges of the flanges. The flanges 9 of the clip extending in the planesof the arms, rest against the inner surfaces of one of the boards ateach side of the sup port, the flanges 8 between the arms, extendbetween the abutting ends of the boards, and the tongues 12 at the endsof the flanges, defined by the weakened lines, are bent in oppositedirections upon the outer surfaces of the boards.

The weakened bending lines of the last mentioned flanges are at adistance from the respective end-members of the clip, slightly less thanthe average thickness of Wall or ceiling boards so that when the tonguesdelined by the lines are bent at right angles upon the outer surfaces ofthe boards, they may be pressed into the material of which the boardsare composed so as to lie flush with the outer surfaces of the same.Thus, the clips may be completely concealed by a filler or filler-stripsused in finishing the structure of which the boards are a part.

The application of the'tongues in the manner shown and described,furthermore draws the boards tightly against the flanges of the supportand the clips secure the boards permanently in alinement and fasten themfirmly and permanently to each other and to the structural supports.

Figures at and 5 of the drawings, illustrate the method of applying theclips to wall or ceiling boards 19 extending to an edge of the support,as, for example, in places where an adjoining board lies flush againstthe face of the body-plate of the support.

The flanges 9 which in the fastening method illustrated in Figures 2 and3, served merely as an additional support for the boards, now functionto secure the boards resting against the flanges, and the flanges 8which in the first described form, were the fastening means, are bentinto the planes of the arms which as before are bent across the outeredges of the flanges. The flanges 9 embrace their ends of the boardsresting against the flanges of the support and the tongues 15 are bentupon the outer surfaces of the boards.

The bending lines are again formed at a distance from the members of theclip, slightly less than the thickness of wall or ceiling boards so thatthe tongues may be pressed into the material of the boards and the endsof the boards may be flush against the crossboard engaging the bodyplate of the structural support.

It will be apparent that the clips formed as shown and described may beapplied in different manners for fastening wall and ceiling boards toeach other and to their supports, that by means of the clips the boardsmay be secured at one side of a support only or simultaneously at bothsides of the same, as the case may be, or that by application of one andthe same clip, wall boards ending at a distance from an edge of thesupport, as in Figure 3, may be fastened at one side of the support anda wall board extending to the edge of the support, as in Figure 4, maybe secured at the opposite side of the support.

The clips may be made of any suitable bendable metal and they may becoated with a rust proof substance if so desired.

It will further be seen, that owing to the provision of the bendablearms, the clips may be applied to structural supports, irrespective ofthe shape or of the width thereof.

What I claim and desire to secure by Letters Patent is:

1. A clip of the character described comprising a body-member, abendable arm at an end thereof, and a flange projecting outwardly fromthe arm, the flange having bendable tongues formed by a slit in theend-portion of the same.

2. A clip of the character described com: prising a body-member,bendable arms at an angle to the body-member at opposite ends thereof,bendable flanges projecting outwardly from the arms, and bendableflanges projecting from the bodyanember, opposite to the arms.

3. Aclip of the character describedformed of a single length of metal,into a bodymember and an end-member at an angle to the body-member,bendable arms formed by slits in the end-member, an outwardly projectingflange formed of the portion of the end-member between the slits,rand aflange extending opposite to the end-member and formed by a cut in thebody-member.

4. A clip of the character described formed of a single length of metal,into a body-member and end-members at an angle to the body-member,bendable arms formed by slits in the end-members, outwardly projectingbendable flanges formed by the portions between the slits, and flangesextending opposite to the end-members, formed by cuts in thebody-member.

5. A clip of the character described comprising a body-member,end-members bent at an angle thereto and divided by slits to formbendable arms and flanges, and flanges formed by bent-out portionsdefined by U- shaped cuts in the body-member adjacent the end-members.

6. A clip of the character described having bendable arms to embrace astructural support and a flange having a weakened line and a slitconjointly defining tongues to embrace wall boards of given thicknessresting against the support.

7. A clip comprising a body-portion, an arm at an angle to the bodyportion, bendable to embrace a flange at an end of a structural support,and a flange projecting outwardly at substantially right angles to thearm, and bendable to embrace an end of a wall board placed against thearm and across the flanged end of the support.

8. A clip comprising a body-portion, an arm at an angle to the bodyportion, bendable to embrace a flange at an end of a structural support,and flanges bendable to project at substantially right angles to thearm, and having their ends bendable to embrace a wall board. placed.against. the arm and across the flanged end of the support, one of theflanges being at the end of the arm at which it adjoins the body portionand another flange being at a point between the ends of the arm.

9. A clip comprising a body-portion, an arm at an angle to the bodyportion, bendable to embrace a flange at an end of a, structuralsupport, and a flange projecting outwardly at substantially right anglesto the arm at the end thereof at which it adjoins the body-portion, andbendable to embrace an end of a wall board placed against the arm andacross the flanged end of the support.

10. A clip comprising a body-portion, an arm at an angle to the bodyportion, bendable to embrace a flange at an end of a structural support,and a flange projecting outwardly at substantially right angles to thearm between the ends thereof, and bendable to embrace an end of a wallboard placed against the arm and across the flanged end of the support.

In testimony whereof I have aflixed my signature.
